Fabrication of Carbon Nanotube and Nanorod Arrays Using Nanoporous Templates

Search this article

Abstract

A simple fabrication process is presented for highly-ordered, highly-oriented carbon nanotube and nanorod arrays by filling alumina nanohole templates with a carbon precursor, polyacrylonitrile (PAN). X-ray photoelectron spectra analysis indicates that PAN changes its chemical structure to sp2 C–C structure after carbonization at 600°C. Raman characterization of the resulting carbon nanostructure demonstrates a high quality graphite structure. The proposed method may be used to develop carbon nanostructure-based devices.
